A 31-year-old employee at South San Francisco High School was arrested on suspicion of sexual misconduct with a minor, police said Tuesday.

Noelia Linares of Richmond was arrested Monday and booked into Redwood City Jail. South San Francisco Police began investigating early last week after receiving reports of “possible inappropriate behavior and relationship(s) between student(s)”and Linares, police said in a a statement.

Police said their investigation identified at least one 17-year-old victim.

Linares’s LinkedIn page says she has worked as an “Instructional Assistant-Bilingual” Spanish translator at South San Francisco High School since September 2011. She previously worked in a similar role at El Camino High School in South San Francisco.

Shawnterra Moore, superintendent of the South San Francisco Unified School District, released a statement notifying the school community of Linares’s arrest.

“We took the appropriate initial disciplinary action, and placed the individual on administrative leave,” Moore wrote. “While we are still learning about the circumstances surrounding the allegations, we are confident that no students are currently in any danger.”

She also wrote that the district believes that the incident was isolated to one school.

Karen Guidotti of the San Mateo County district attorney’s office said prosecutors have not yet received the case from police.

The investigation is ongoing, and no additional details were released.
